WICHITA, Kan. (AP) – A federal judge has designated the case of a man accused in a suicide bomb plot at a Kansas airport as “complex.”

U.S. District Judge Monti Belot made the ruling Tuesday in the case of Terry Loewen, a 58-year-old avionics technician facing terrorism-related charges. Such a designation eases speedy trial concerns and allows the parties more time to prepare their cases.

Belot noted in his decision that discovery is sizeable and involves declassified and sensitive evidence.

Loewen was arrested Dec. 13 after allegedly trying to bring a van filled with inert explosives onto the tarmac at Wichita’s Mid-Continent Airport.

He has pleaded not guilty to attempting to use a weapon of mass destruction, attempting to use an explosive device to damage property and attempting to give material support to al-Qaida.
